This is a program to compute intermediate surfaces between two boundary surfaces SurfLayers computes new surfaces for a given number of cortical divisions at intermediate distances by simple computation of the fraction between the inner and outer-most surfaces (aka "equi-distant"). A single dividing surface would be halfway between the two surfaces.
-spec SPEC_DSET :dataset that is the SUMA specification file describing input surfaces -outdir DIRNAME :new directory for output (default: surflayers) -states IN OUT :typically smoothwm, pial states to describe inner and outer surfaces (default: "smoothwm pial") -hemi HH :choose hemisphere: "lh", "rh" or "lh rh" (for both) -n_intermed_surfs N :total number of intermediate surfaces to create -surf_A SB :inner boundary surface by filename (e.g. smoothwm.gii) -surf_B SA :outer boundary surface by filename (e.g. pial.gii) -surf_intermed_pref SIP :name for interpolated surfaces (default: isurf) -echo :run script with 'set echo' (i.e., verbosely) -no_clean :do not remove temp files (probably just for testing)
Output includes a new directory containing: + isurf.lh.01...n.gii - interpolated surfaces numbered 1 to n + other files too if -spec option was utilized + a run*tcsh script to view the output directly See also the quickspecSL program for creating a *.spec file.
